I think the ACSD guide makes it seem like you need a 70m, but as Adam K. pointed out a 60m rope will get you from the rap anchors on the top of the Video Dome to the base of this climb. Tie knots if you're not sure where you're going.

There are no bolts between the anchor for this climb and the top set of rap anchors, but it is 5.easy terrain. Belaying your 2nd up to the higher set of anchors makes for an easier walk back to El Nino.

The trail leading to the video dome base has been re-opened after many years of neglect as of dec 26th 2017 It is now possible to approach video dome area and the solar slabs area as well as the main wall, without multiple rappels. The trail begins just past the saddle boulders and heads south towards a large Boulder then follow cairns down the hill traversing a few hundred feet below the El Niño formation. Enjoy the trail everyone
